Item Type: Switch Type: Normally Closed Temperature Range: 40~130C Contact Load: 220VAC 1.5A or 24VDC 1.5A Insulation Resistance: 50M at normal temperature and humidity Contact Resistance: 100m Electric Strength: 500VAC Temperature Options: D40 / D45 / D50 / D55 / D60 / D65 / D70 / D75 / D80 / D85 / D90 / D95 / D100 / D105 / D110 / D115 / D120 / D125 / D130 (Optional) Package List: 1 x Switch Installation and Usage Notes: - When using contact temperature sensing, ensure the metal cover is in close contact with the mounting surface of the controlled appliance. For optimal performance, apply thermal grease or a similar heat-conductive medium to the temperature-sensitive surface. - Avoid crushing, loosening, or deforming the top of the cover during installation to prevent performance issues. - Do not allow liquid to penetrate the temperature controller. Do not crack the housing or alter the shape of the external terminals. - Use the product in circuits with a current of no more than 5A. Use copper wire with a cross-sectional area of 0.51mm. For circuits up to 10A, use copper wire with a cross-sectional area of 0.751.5mm. - Store the product in a clean, dry, well-ventilated area with a relative humidity below 90% and an ambient temperature below 40C. Ensure the storage environment is free of corrosive gases.
